2021-11-29RDMA/bnxt_re: Use bitmap_zalloc() when applicableChristophe JAILLET1-4/+2
Use 'bitmap_zalloc()' to simplify code, improve the semantic and avoid some open-coded arithmetic in allocator arguments. Also change the corresponding 'kfree()' into 'bitmap_free()' to keep consistency.

2021-11-29RDMA/pvrdma: Use non-atomic bitmap functions when possibleChristophe JAILLET1-3/+3
In 'pvrdma_uar_table_init()', the 'tbl->table' bitmap has just been allocated, so no concurrent accesses can occur. The other accesses to the 'tbl->table' bitmap are protected by the 'tbl->lock' spinlock, so no concurrent accesses can happen. So prefer the non-atomic '__[set|clear]_bit()' functions to save a few cycles.

The RoCE spec requires RoCE devices to support only the default pkey. However the bnxt_re driver maintains a 0xFFFF entry pkey table and uses only the first entry.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq fixes from Thomas Gleixner: "A set of fixes for the interrupt subsystem Core code: - A regression fix for the Open Firmware interrupt mapping code where a interrupt controller property in a node caused a map property in the same node to be ignored. Interrupt chip drivers: - Workaround a limitation in SiFive PLIC interrupt chip which silently ignores an EOI when the interrupt line is masked. - Provide the missing mask/unmask implementation for the CSKY MP interrupt controller. PCI/MSI: - Prevent a use after free when PCI/MSI interrupts are released by destroying the sysfs entries before freeing the memory which is accessed in the sysfs show() function. - Implement a mask quirk for the Nvidia ION AHCI chip which does not advertise masking capability despite implementing it. Even worse the chip comes out of reset with all MSI entries masked, which due to the missing masking capability never get unmasked. - Move the check which prevents accessing the MSI[X] masking for XEN back into the low level accessors. The recent consolidation missed that these accessors can be invoked from places which do not have that check which broke XEN.
